TelCom Semiconductor TC1240

The TC1240 is a doubling CMOS charge-pump voltage converter in a small 6-Pin SOT-23A package. The TC1240 has an active high shutdown which limits the current consumption of the device to less than 1µA. TC1240-1 7/7/00 2 Positive Doubling Charge Pump with Shutdown in SOT Package TC1240 DETAILED DESCRIPTION The TC1240 charge pump converter doubles the voltage applied to the VIN pin.
